What if you could reduce the size of all the jpeg pictures on your hard disk? Do you have problems sending full resolution jpeg images via email because of size restraints? Is your iPhoto library too large? Let’s face it; pictures is one of the things that sucks up space on your drives. It’s even more annoying if you are using a newer Mac with an SSD disk where cost is premium. Upload speed when sending emails or uploading images to the web can be slow and annoying. An application called JPEGMini claims to help you with reducing your pictures with up to five times while retaining all the quality. I got a bit curious if the team at JPEGMini and their patented image compressor really could reduce large JPEG photos without losing quality. I’ve tried the application before when I wrote my article about comparing the best jpeg compressor applications for web use. But even though JPEGMini is geared more towards large megapixel pictures, not small images usually used on web pages, my test shows that it stacks up well against the competition even on more modest photographs. Many web pages now use pictures optimized for high-resolution images like for Retina display and high-resolution mobile devices, so the use of an image compressor is getting even more useful for web use.
But how well does JPEGMini retain quality on megapixel images in JPEG format? How much do you lose in quality by using compressing?
